Please cherry-pick:

Please cherry-pick:
- all extra email address validators (so not the generic one) have no attribute
  "allowEmptyRequiredData" anymore as the email address for them (e.g. branch
  office) is always optional
- converted own JSF tag core:outputAdminContactDataFormFields to template again
- reformatted some JSF tags to have each attribute in a single line
- the gender-specific backing bean was superflous since there is a "static
  data" backing bean
- added missing i18n string COUNTRY_POLAND (country was added in JFinancials)
- fixed tpzo in i18n key
